KFM 10: Focus session: Polar Materials Meet Energy demands

Dienstag, 6. September 2022, 09:30–12:25, H5

Polar materials, in particular in (anti-) ferroelectrics, play an important role in future energy storage and energy harvesting devices and have a high potential for ultra-low power memory and logic devices as well as energy efficient cooling technologies. The aim of this focus-session is to bring together scientists from theory and experiment to improve the fundamental understanding and optimization of the underlying material properties and microstructures in a multiphysics and multidisciplinary scenario.

Organizers: Prof. Dr. Anna Grünebohm (Bochum) and Prof. Dr. Bai-Xiang Xu (TU Darmstadt)

Chair: Prof. Dr. Anna Grünebohm (Bochum University)
